Item Settings
Specify the COM port No. of a master unit, MODBUS command to be
S1
sent, and the unit number of a destination unit.
Specification of
S2
a master unit
Specification of
D a destination
unit
Specification of
n a destination
unit
(Note 1) In [S1], specify the combination of the COM port No. of a master unit, MODBUS function code and the
unit number of a destination unit. When the COM port No. is 0, specify HF for the highest digit.
Example: In the case of COM port 1, MODBUS function code 6, and destination unit No. 10, specify
H160A.
COM port selection (upper four bits)
Port no.
(Note 2) Depending on the operation memory type specified in operand [S1] and the number of send data
specified in operand [n], the transfer method and the function code of MODBUS command to be sent
vary.
Device type specified
in [S2]
16-Bit device:
WX, WY, WR, WL, DT,
LD
1-bit device
X, Y, R, L
(Note 3) When "0" is specified for the destination unit number, global transfer is applied. In this process, there is
no response message from a destination unit.
(Note 4) For the number of send data [n], specify the number of words in the case of register transfer, and
specify the number of bits in the case of bit transfer.
